Application of chaos and extension theory to fault diagnosis of three-phase synchronous generators

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2020
This study applied an extension algorithm combined with the Chaos Theory to the fault diagnosis of the three-phase synchronous generator. First, the three-phase synchronous generator is classified, including normal, carbon brush fault, three-phase ...

Weakening Assumptions for Deterministic Subexponential Time Non-Singular Matrix Completion [PDF]

open access: yes, 2009
In (Kabanets, Impagliazzo, 2004) it is shown how to decide the circuit polynomial identity testing problem (CPIT) in deterministic subexponential time, assuming hardness of some explicit multilinear polynomial family for arithmetical circuits.

Equivalent Circuit Theory-Assisted Deep Learning for Accelerated Generative Design of Metasurfaces

open access: yesIEEE Transactions on Antennas and Propagation, 2022
In this article, we propose an equivalent circuit theory-assisted deep learning approach to accelerate the design of metasurfaces. By combining the filter equivalent circuit theory and a sophisticated deep learning model, designers can achieve efficient metasurface designs.

VOLT-AMPERE CHARACTERISTIC AND INDUCED CURRENT IN THE EXTERNAL CIRCUIT OF AVALANCHE-GENERATOR DIODES ON THE BASIS OF THE BACK DISPLACED ABRUPT P–N-JUNCTIONS [PDF]

open access: yesРадиофизика и электроника, 2015
Creation of modern solid-state microwave power sources is based on the application of active elements with expanded functionality. The reverse-biased p–n-junctions with DC voltage are active elements of diodes generators. Avalanche-generator diodes (AGD)
